LIQUID-DISPENSINGAPPARATUS.

Application filed December 5, 1923. Serial No. 678,587.- j

tains, etc l, carrying on a retail trade. The

objects, of the invention are to provide apparatus of thischaracter which maybe economically built, easily and accurately op'er" ated, which shall dispense at each operation substantially the same' amount-of liquid, in

which the'liquid maybe kept'cool and re, freshing, and whichlshallbe' satisfactorily sanitary. I

Our invention also relates to apparatus of thischaracter from which the drip of the dispensed liquid'shall be eliminated.

The annexed drawings and the following descriptionset forth in detail certain means embodying our invention, such means constitutiug, however, but" one of the-var ous forms in which the principle of the invention may be applied.

In saidannexeddrawings:

Figure 1 represents a-vertical longitudinal section of our improved apparatus, taken in the planes indicated by the line II, Figures 2 and 5;

"Figure, 2 represents a plan section, taken in the. planes indicated by the line III I', Figureilr V Figure 3 represents a fragm'entaryfront e'levation,-taken from the plane indicated by thelineIII'III, Figural; v

Figure 1 represents'a sectionsimilar to Figure 1, but showing'the, scoop or bucket'in discharging position, one of theupper positions of the scoop and bucket being also shown in dot and dash lines just previous to the tilting of the bucket; Figure 5 represents a vertical transverse section, taken in the planes indicated by: the line VV,-Figure 1; and 7 f Figure 6 represents a front. elevation, taken from the plane indicated by'the line VI VI,Figure 4. I v V 4 Referring to the annexed drawings in which the same parts are indicated by the same respective ordinal's in the several'views, we indicated a main casing by the ordinal 1 having an upper cover 2 through which the liquid to be dispensed may be poured for filling a liquid reservoir 3 separated from an ice chamber 4: by a partition 5, said-ice chamber 1 being provided with an upper cover 6 for a filler ripening, and a drain 7 The ervoir 8 is formed with a well 8 from which isscooped by a bucket9 portionsfof't-he 1i'quid 10 which areintended by the liftingand vtilting of the bucket '9 to: be discharged through the case opening 11 into a suitable serving. receptacle such as a glass or cup held by the operator adjacent to and exteriorly of tlie ope ningl l. This raising and dumping of the'bu'cket 9 is effectedby "the operator whenthe'pivoted cover 12 adapted to close the opening 11 is lifted by the operator to uncover said opening 11. The actual con-' nectionbetween the cover 12 and thebucket' so as to actuate the latter upon theinovemen't of the'cover 12 is as:follows; a lug12 is se-' curedto the inner face of thecover 12 and I pivoted to this lug is a link lg running back substantially to the rear of the chamber 3 l and connected at itsrear end to a short rear wardly-extending arm lfl whose other and front end is fixed toatra'nsverse shaft 15. Alsofix'ed to this shaft 15 is one end'of a lever o'r arm 16 formed at its other end with a a U-shaped member having arms-18"an'd-18f.

lever 161With the distance from theopening" 11 tothe shaft 1 5 and the comparative heights of the'sh'a'ftf 15am the bottom edge oftheopening 11 are such as to cause the bucket 9 just beforereachingits extreme upper position to be positively dum'pedby the upward lifting of the rear of theloucket 9, as plainly shown in Figure 4. It is evident that the dropping or closing'of the cover 12will effect through the elements18,145, 15 and 16" i a therealignment of the bucket and the transi fer of thesame to the lower; position shown in'Figure' 1. The actual operation} of the cover 12 may beeffectedby power m'ejans "or manually in anysuitable manner and we have shown as one'exampleof the same a handle 22 secured to the cover 12 and having a hand grip 23. As plainly shown in Figure 1,the

filler cover 2 is pivoted at its front end upon serve to define the lower side walls of the opening 11. When the cover 2 is lifted to fill the chamber 3, the discharge opening cover 12 which is pivoted at its upper end 26 to the cover-'2 is also lifted and this movement of the cover 12 will bring the bucket 9 and connected elements into the position shownin dot and dash lines, Figure 1, which positions will also help to explain the operative connection of the cover 12 and bucket 9.

Referring to the form of bucket shown by applicants, it is particularly adapted for shown in Figure 5.

the dispensing of cream for coffee, etc., in which operations, of course, only. a small part of the cup or receptacle is filled with the dispensed liquid so that there is little liability of any slopping occurring. Inthis form of bucket it will be noted that the discharge mouth is provided adjacent one end of the bucket, that the charge chamber is positioned at the opposite end of the bucket and that assuming that the diameter of the bucket is maintained constant. The object of this construction is to make buckets for charges of varying sizes, the buckets to have a uniform diameter. Therefore, if it is desired to change the size of the char e, a bucket is-substituted for the one in use which shall have a filler opening 9 cut atthe proper I height, when the bucket is held in vertical )osition to rovide the size of the char e desired. It is evident that when the buckets are held in vertical position, all of the contents thereof above the line 36 will runout. lVc plainly show in Figures 1,- 2. 4., and 5 means for readily replacing the buckets 9. It would be impracticable, of course, to. spring the yoke arms 18 and 18 sufiicient to remove the bucket 9, so that we make one of these arms 18 a readily removable member from the arm 18 and also readily again attached. This construction is plainly Now, inasmuch as all of the buckets 9 are of uniform diameter. the size of the charge being determined by the position of the wall 36, it is evident that the one bucket support 161818' will serve for buckets holding all of the desired to the bucket-supporting means so as to effect the raising of said supporting means as the cover is being opened, and the loweringof said. supporting'means as the cover is being closed, and means for tilting the bucket to discharge through said opening when the cover has; been fully opened, said tilting means realigning the bucket as the latter is again lowered- I 2. In liquid dispensing apparatus, the combination of a liquid receptacle formed with a discharge opening; clined guide in which. said bucket is adapted to travel a forked support in which said bucket is pivoted; means for tilting the bucket; a pivotallymounted cover for said dischar e opening; and means for open- 'ing; and closing said cover, said last-mentioned means being connected to the bucket supporting and tiltingmeans so as to effect the raising of said supporting means and the tilting of the bucket to discharge through said opening when the cover is opened and the realigning of the bucketand the lowering of the latter while said cover is being closed. 1

3. In liquid dispensing apparatus, I the combination of a liquid receptacle formed with a side discharge opening; a bucket; a forked support in which said bucket is pivoted at one end; a shaft journalled in the walls of said receptacle, the other'end of the bucket support beingsecured to said shaft; a pivotally-moui'ited cover for said discharge opening; a rearwardly-e-Xtending arm secured to said shaft; and a link'pivotally connected to said cover and to said arm, the length of said bucket support being less than the distance betweensaid discharge opening and-said shaft so that the bucket is tilted when the forkedend of its support is raised above said discharge opening.
